Radiofrequency ablation of varicose veins improves venous clinical severity score despite failure of complete closure of the saphenous vein after 1 year

Summary Background and objectives Endovenous treatment is increasingly supplanting open surgery for the treatment of varicose veins. Among emerging endovenous techniques, radiofrequency ablation (RFA) with a ClosureFast catheter is popular in Korea. The objective of this study was to evaluate and co...

Description
Summary:Summary Background and objectives Endovenous treatment is increasingly supplanting open surgery for the treatment of varicose veins. Among emerging endovenous techniques, radiofrequency ablation (RFA) with a ClosureFast catheter is popular in Korea. The objective of this study was to evaluate and compare the efficacy and patient-reported outcomes of RFA of varicose veins. Methods This is a retrospective study of a prospectively registered database of patients who underwent RFA for varicose veins from 2012 to 2013 in St. Mary's Hospital in Seoul. Korea. Efficient ClosureFast RFA catheters (Medtronic, San Jose, CA, USA) were used. The techniques used for RFA of varicose veins were performed according to the manufacturer's recommendations. Duplex scans and venous clinical severity scores (VCSSs) were used to document treatment outcome and patient symptoms before and after the procedures. Treatment outcomes were estimated before the procedure and 3 months, 6 months, and 12 months after the procedure. Outcomes were analyzed by paired t test, chi-square test, or Fisher's exact test as well as by logistical regression. Results A total of 117 patients were evaluated for 183 consecutive RFA procedures (183 limbs). The initial technical success was 97.3% (178/183). The estimated mean VCSS changed over time from 4.0 ± 1.67 at preprocedure to 0.6 ± 1.05, 0.5 ± 1.02, and 0.6 ± 1.14 at 3 months, 6 months, and 12 months after the procedure, respectively. The improved VCSS was maintained 1 year after the procedure ( p
